Remote Annunciator

ANNUNCIATOR DESCRIPTION

The remote annunciator is available in the following versions:

0G5719 - Remote Annunciator• has both relays and LEDs/

Keypad (RRP & RAP)

0G5720 - RRP version• - Remote Relay Panel (Relays with no

LEDs/Keypad)

0G5721 - RAP version• - Remote Annunciator Panel (LED's/

Keypad without relays J1 - J8)

The Remote Annunciator provides remote monitoring and annun-

ciation of up to 18 generator parameters using the lights/LEDs

located on the annunciator keypad. Selected generator parameters

can be annunciated using the eight Form A relays provided on

0G5719 and 0G5720.

The Remote Annunciator also provides two system-level warn-

ings which are System Ready and Communications OK. Multiple

annunciators can also be connected to obtain remote monitor-

ing and annunciation of all 18 generator parameters. Power to

the remote annunciator is supplied from the generator battery

(+12VDC or +24VDC).

Communication with the Remote Annunciator is via a RS485 serial

data link. The remote annunciator is typically configured for listen

only mode (also called slave or passive mode). In this operat-

ing mode, the annunciator receives information on the generator

status, from the generator controller and activates/deactivates the

relay outputs to reflect the status of up to eight selected generator

parameters. The remote annunciator can also be configured to

request status information from the generator (called master or

active mode).

The specific faults to be annunciated using the relay outputs (J1

- J8) can be selected using either the DIP switches located on the

annunciator printed circuit board, or the Graphical User Interface

(GUI) available using a computer via the RS232 connector on the

annunciator printed circuit board (see Figure 2).

Relays J1 - J8 provides a set of normally open contacts. All relays

are energized (contacts closed) when power is applied to the

annunciator. The relay selected to annunciate a particular fault will

then open during a fault.

The terminal block connections (J10), used to connect the battery

supply and the RS485 communication lines to the remote annun-

ciator are shown in Figure 1. The location of DIP switches S1, S2,

S3 and S4 and the RS232 connector are shown in Figure 2.

INSTALLATION AND MOUNTING

NOTE:

3. For ALL models installation must always comply with

applicable codes, standards, laws and regulations. Adhere

strictly to local, state and national electrical and building

codes. Comply with regulations the Occupational Safety

and Health Administration (OSHA) has established. Also,

the generator and related components must be installed

completely in conformance with the manufacturer’s instruc-

tions and recommendations. Following proper installation,

do nothing that might alter a safe installation and render the

unit in non-compliance with such codes, standards, laws and

regulations.

4. The plastic knockout that is used to route the wires and

cables into the annunciator should be removed with the

annunciator firmly supported by placing it on a flat surface.

5. Wire tie-downs are provided in two places on the base of the

annunciator to provide strain-relief for the connecting cables

and wires (Figure 3).

RELAY ANNUNCIATION (J1 - J8)

The user can select up to eight of the following 18 generator

parameters to annunciate via the relays, when the 10 position (S1)

and the 8 position (S2) DIP switches on the annunciator PCB are

being used.

PARAMETERS S1.1 - S1.10 & S2.1 - S2.3 

When a remote annunciator (0G5719) or Remote Relay Panel

(0G5720) is used in a Modular Power System (MPS), an alarm on

any one of the generators causes the associated relay to activate.

PARAMETER "GENERATOR RUN" 

This parameter is defined as any one or more generators in the

system running.

PARAMETER "GENERATOR POWER" 

This light/LED indicates different things depending on the type of

system it is attached to.

It is defined as whether the Transfer Switch is in the Generator • Supply Position.

For a PowerManager System Controller (PM-SC with external • transfer switch(es)), generator power is defined as any one or

more generators in the system running and connected to the

generator bus.

For a non-paralleling engine controller (PM-GC • WITHOUT inter-

nal transfer switch), it represents the status of input 4 (TB2-5)

to the generator controller. This should be connected to the gen-

erator side auxiliary contact of the external transfer switch. A

closure to ground will cause the light to illuminate. This shows

whether the load is powered by the generator.

For an engine controller that is part of an MPS system, genera-• tor power represents the state of the internal contactor that the

generator is connected to.

PARAMETER "LINE POWER" 

This light/LED indicates different things depending on the type of

system it is attached to.

Is defined as whether the Transfer Switch is in the Utility Supply • Position.

For a Power Manager System Controller (PM-SC with external • transfer switch(es)), line power represents the auxiliary input

C (TB6-4).

For a non-paralleling engine controller (PM-GC WITHOUT inter-• nal transfer switch), it represents the status of input 3 (TB2-4)

to the generator controller. This should be connected to the

utility side auxiliary contact of the external transfer switch. A

closure to ground will cause the light to turn ON. This shows

whether the load is power by the utility.

For an engine controller that is part of an MPS system, line • power is not used.

PARAMETER “BATTERY CHARGER AC FAILURE” 

This light/LED annunciates upon loss of 120VAC power supply to

the battery charger and is communicated to the Annunciator by the

generator controller.

GENERATOR STOP INDICATORS

These lights/LEDs will flash when any alarm occurs and the horn

will sound as follows:

Annunciator Light Light Color Audible Alarm

RPM Sensor Loss Red Yes

Overcrank Red Yes

Overspeed Red Yes

Low Oil Pressure Red Yes

High Water Temp Red Yes

Low Water Level Red Yes

Emergency Stop Red Yes

NOTE:

7. Both the High Water Temp and the Low Water Level LEDs will

turn ON if either fault condition is present.

The "Re-arm Horn" switch can be used to turn off and re-arm the

horn, or the alarms can be fully acknowledged using the "Reset"

switch.

The "Reset" switch will turn off and re-arm the horn, and any flash-

ing lights will switch to the ON state until the alarms are no longer

present at the generator control panel.

NOTE:

8. The alarm condition must be reset at the generator control

panel.

9. When this annunciator is used in a Modular Power System

(MPS), an alarm on any one of the generators will cause the

lights/LEDs to light, and alarms to sound.

WARNING INDICATORS

These lights/LEDs will flash when any alarm occurs and the horn

will sound according to the following table:

Annunciator Light Light Color Audible

Alarm Latched

Pre-low Oil Pressure Yellow Yes Yes

Pre-high Water Temp Yellow Yes Yes

Pre-low Water Temp Yellow Yes Yes

Pre-low Fuel Yellow Yes Yes

Battery Charger AC

Failure Yellow Yes No

Low Battery Voltage Yellow Yes No

High Battery Voltage Yellow No No

Generator Run Yellow No No

Generator Power Yellow No No

Not in Auto Red Yes No

Remote Annunciator

These alarms will be latched/not latched by the annunciator

according to the above table. They can be acknowledged at the

annunciator using the ‘Reset' switch—the active lamps will then

stop flashing and remain in the ON state until the alarm signal

clears from the generator control panel. The "Reset" switch will

also turn off and re-arm the horn.

NOTE:

10. These lights can only be fully reset when the alarm state

is no longer active and “Reset” has been pressed at both

the generator control panel and the remote annunciator.

Alternatively, at any time the horn can be turned OFF and

re-armed with the "Re-Arm Horn" switch.

11. When this annunciator is used in a Modular Power System

(MPS), a warning on any one of the generators will cause

the above lights to light, and alarm to sound (if the warning

is audible).

SPARE INDICATOR

The spare indicator light/LED can be activated from the PM-GC or

PM-SC by using the Integrated Logic Controller (ILC) feature in the

G-panel or H-panel. Also see the section in this manual describing

the operation and set-up of the spare keypad switch.

Annunciator Light Light Color Audible Alarm

System Ready Green Yes

Communication OK Green Yes

Line Power Green No

Spare Green No

SYSTEM STATUS INDICATORS

These lights/LEDs are for Status indication only—the normal

condition is ON.

SYSTEM READY 

The System Ready is defined as ALL “in service” generators are

ready to start, run, and supply power. Any generators manually

declared as “out of service” will not affect this LED.

Upon a loss of System Ready, the annunciator will respond as

follows:

1. The System Ready LED will begin to flash.

2. The alarm will sound.

The “Re-arm Horn” switch can be used to turn off and re-arm

the horn, or the alarm can be fully acknowledged using the reset

switch at which time the System Ready LED will turn off and

remain off until the System Ready status is returned.

COMMUNICATION OK 

This LED will be ON as long as there is proper communication

between the Remote Annunciator Panel and the Generator control

system. It typically requires less than a minute for the Annunciator

to determine the correct baud rate and connect to the RS485

bus.

When communication failure occurs, the Annunciator will flash the

communication LED, and sound the horn. The rate of flashing will

be indicative of the cause of error.

1. No reply from the generator control system, Frequency = one

second ON/one second OFF

2. Consecutive data errors, Frequency = 0.5 second ON/two

seconds OFF.

This alarm condition can be acknowledged at the Annunciator

using the “reset” switch - the horn will be turned off and re-armed,

and the communication OK light will continue to flash until proper

communication returns.

GREEN STATUS LED (INTERNAL TO UNIT) 

If the green LED is flashing at a one second on and one sec-• ond off rate, the unit is operational and is configured from the

Windows Graphical User Interface.

If the green LED is flashing at a one second off and five seconds • on rate, the unit is operational and is configured from the DIP

switches.

If the green LED is flashing at a half second on and five seconds • off rate, the unit is operational but there are no RS485 com-

munications.

If the unit is powered for 30 seconds and the Green Status LED • does not turn on at all during this time, the circuit board is not

functional.

SYSTEM KEYPAD SWITCHES

TEST SWITCH 

While the test switch is pressed, all lights/LEDs will light and the

horn will sound. When released the lights/LEDs will return to their

original status. During this test, communication to the generator

control system will be suspended.

RE-ARM HORN SWITCH 

The re-arm horn switch will silence the alarm horn and re-arm it

for new alarm occurrences.

RESET SWITCH 

The reset switch is used to acknowledge any active alarms. It will

re-set any flashing light/LED’s to a ON (steady) condition (or OFF

for normally on lights). If the alarm no longer exists and it has also

been latched OFF at the generator control panel (pre-alarm indica-

tors only) the active light will go OFF. It will also silence the horn

and re-arm it for new occurrences.

Remote Annunciator

NOTE:

12. Pre-alarm conditions MUST be reset at the generator set

control panel.

SPARE KEYPAD SWITCH 

When DIP Switch S3, Position 4, is in the ON position, it allows the

SPARE Keypad Switch to control Relay 8. When this DIP switch is

in the ON position, pushing the SPARE keypad Switch will energize

Relay 8 and turn on the spare light/LED on the keypad. Pushing

the SPARE keypad Switch again will de-energize Relay 8 and turn

off the spare light/LED. NOTE:

13. The Remote Start capability using the Spare Keypad Switch

and Relay 8 is only available when Remote Annunciator

version P/N 0G5719 is used.

OTHER FUNCTIONS

GRAPHICAL USER INTERFACE (GUI) OR DIP SWITCHES ENABLED - DIP SWITCH S3-1

When Position 1 is in the ON position the Graphical User Interface

(GUI) must be used to set the relay fault conditions. When Position

1 is in the OFF position the DIP switches on the Annunciator con-

trol board must be used to set the relay fault conditions.

MASTER/SLAVE MODE - DIP SWITCH S3-3 

Position 3 is used to configure the Annunciator as either a Slave

(OFF position) or as a Master (ON position). In Slave mode, it is

a Modbus slave and must be connected to a master port on the

PM-GC or PM-SC. This method allows for the connection of more

than one Annunciator. In Master mode, the Annunciator is the

Modbus master and will request data from the PM-GC or PM-SC.

The PM-GC or PM-SC must be set as a slave port when the

Annunciator is configured as the Master (Figures 10 and 11).

SPARE KEYPAD SWITCH - DIP SWITCH S3-4 

Position 4, when it is in the ON position, it allows the SPARE

Keypad Switch to control Relay 8. When this DIP switch is in

the ON position, pushing the SPARE keypad Switch will energize

Relay 8 and turn on the spare LED on the keypad. Pushing the

SPARE keypad Switch again will de-energize Relay 8 and turn off

the SPARE LED. This feature can be used to implement a Remote

Start function. This Remote Start feature is only available with the

Remote Annunciator version (0G5719) that has both the Relays

and the Keypad.

BAUD RATE SELECTION (DIP SWITCH S4) 

DIP Switch S4 can be used to set the Communications Baud Rate

to a pre-determined value (see table).

S4-1 S4-2 Baud Rate

OFF OFF Auto-Baud Rate detect (max rate is 57600)

OFF ON 38400

ON OFF 9600

ON ON 4800

Remote Annunciator

ALARM RELAY (J9) 

The Annunciator provides a relay with both a Normally Open con-

tact and a Normally Closed contact. This relay is energized when

DC power is provided to the Annunciator so that in the event power

to the Annunciator fails the relay contacts will change state. When

the Audible alarm is activated this relay will be de-energized.

RS485 LINE TERMINATION RESISTOR 

A 1000 ohm RS485 terminating resistor is installed on the Remote

Annunciator PC board via a 3-position jumper (JMP1 in Figure 2).

In most applications this 1000 ohm terminating resistor is con-

nected and the jumper (JMP1) is in the closed or 1-2 position. This

jumper can also be moved to the open or 2-3 position.

GRAPHICAL USER INTERFACE (GUI) 

A DB9 connector is provided on the Annunciator Control Board for

use in setting the Annunciator functions. A GenLink serial cable

(P/N 0F7707) should be used to connect a laptop computer’s

RS232 serial port to the Annunciator DB9 connector. The GenLink

cable is a Null-Modem style serial cable with female-to-female

DB9 connectors.

Shown in Figure 12 is a typical Windows GUI interface as it

appears on the computer display.

RS485 COMMUNICATIONS 

In a typical application, the Annunciator monitors (i.e. slave mode)

the Generator control system via the RS485 communication line.

SERIAL INTERFACE 

Baud Rate Auto-Detect 57.6K, 38.4K, 9600

or 4800 (No Parity, 2 Stop Bits)

COMMUNICATIONS CONNECT TIME 

When an Annunciator is powered up onto an existing RS485

network, there will be a period of time, during which the unit may

report a “communication failure”. During this time the Annunciator

is searching for the correct Baud rate. The Annunciator will typi-

cally communicate within one minute after being connected.

Remote Annunciator

Figure 12 — Annunciator GUI Interface Display

Remote Annunciator

ERROR HANDLING 

An error will be reported by flashing the Communication OK light—

the rate of flashing will be indicative of the cause of the error.

1. No reply from generator control system—frequency one sec-

ond on/one second off.

2. Consecutive data errors—frequency 0.5 seconds on/two sec-

onds off.

The Annunciator, if configured for auto-baud rate detect, will try

several times at each of four different baud rates (57.6K, 38.4K,

9600 and 4800) before reporting a communication error by de-

energizing all the relays and then flashing the Communication OK

light.

LIMITS OF OPERATION 

The following communication restrictions apply for multiple units

on a common RS485 line:

A maximum of 15, 1000 ohm RS485 Loads (i.e. 57.6K • Annunciator, G-panel, H-panels, etc) can be connected to the

RS485 bus at one time. NOTE:

14. There MUST be only ONE (1) master in the RS485 com-

munication bus. All others must be slaves (PASSIVE).
